Colorado Springs & Cripple Creek (9 Tunnels)

The Colorado Springs & Cripple Creek District Railway was built from 1897 to 1901 between its namesake cities. The railroad served the gold mining district of Cripple Creek and Victor, competing with the narrow gauge Florence & Cripple Creek Railroad (1894-1912) and standard gauge Midland Terminal Railway (1894-1949). Following abandonment, much of the grade was repurposed as a toll road in 1926 and later became the Gold Camp Road (County Road 8). The CS&CCD required a total of nine tunnels, three of which are still open to automobile traffic, all pictured below.
